“…In our study, all participants were asymptomatic, however, the results of the vision screening elucidated the presence of mild binocular and accommodative disorders in most of them. This is in line with the latest reports on the prevalence of binocular and accommodative disorders among the population ( Paniccia & Ayala, 2015 ; Hussaindeen et al, 2017 ; Magdalene et al, 2017 ; Atiya et al, 2020 ). Namely, it was estimated that the non-strabismic binocular vision anomalies are present in at least one third of the young population ( Cacho-Martínez et al, 2010 ; Hussaindeen et al, 2017 ; Magdalene et al, 2017 ; Atiya et al, 2020 ), and prevalence increases with age ( Hussaindeen et al, 2017 ).…”

Accommodative anomalies are even more widespread – reaching nearly two-thirds of population ( Cacho-Martínez et al, 2010 ; Paniccia & Ayala, 2015 ).…”

“…Over recent years, the interest toward investigating binocular and accommodative disorders has increased revealing that many cases of imbalance in the visual functions remain undiagnosed or underdiagnosed due to different reasons ( Cacho-Martínez, García-Muñoz, & Ruiz-Cantero, 2010 ; Paniccia & Ayala, 2015 ; Hussaindeen, Rakshit, Singh, George, Swaminathan, Kapur, Scheiman, & Ramani, 2017 ; Magdalene, Dutta, Choudhury, Deshmukh, & Gupta, 2017 ; Atiya et al, 2020 ). First, the patients may have no symptoms or complaints.…”

“…Most often individuals accommodate or converge less than required, which may affect spatial judgments in the presence of vergence-accommodation conflict due to recalibrated weights of the depth cues ( Horwood & Riddell, 2014 ). The individuals are often unaware of binocular and accommodative disorders due to the absence of symptoms ( Horwood & Riddell, 2008 ; Chandra & Akon, 2016 ; Atiya, Hussaindeen, Kasturirangan, Ramasubramanian, Swathi, & Swaminathan, 2020 ). Moreover, visual acuity and stereoscopic acuity, commonly used as the inclusion criteria in the studies on human factors in stereoscopic augmented reality, can be according to clinical norms ( Scheiman & Wick, 2013 ).…”

New visualization approaches are being actively developed aiming to mitigate the effect of vergence-accommodation conflict in stereoscopic augmented reality; however, high interindividual variability in spatial performance makes it difficult to predict user gain. To address this issue, we investigated the effects of consistent and inconsistent binocular and focus cues on perceptual matching in the stereoscopic environment of augmented reality using a head-mounted display that was driven in multifocal and single focal plane modes. Participants matched the distance of a real object with images projected at three viewing distances, concordant with the display focal planes when driven in the multifocal mode. As a result, consistency of depth cues facilitated faster perceptual judgments on spatial relations. Moreover, the individuals with mild binocular and accommodative disorders benefited from the visualization of information on the focal planes corresponding to image planes more than individuals with normal vision, which was reflected in performance accuracy. Because symptoms and complaints may be absent when the functionality of the sensorimotor system is reduced, the results indicate the need for a detailed assessment of visual functions in research on spatial performance. This study highlights that the development of a visualization system that reduces visual stress and improves user performance should be a priority for the successful implementation of augmented reality displays.

“…Additionally, similar experiences and symptoms may occur due to accommodation anomalies, that also result in a failure to maintain a focused retinal image. Overall, more than 30% of the population have moderate to poor stereo vision (stereoanomaly: Hess et al, 2015) due to vergence and accommodation anomalies typically combined with a refractive error (Atiya et al, 2020;Dahal et al, 2021;Franco et al, 2021).…”

Full accessibility to eXtended Reality Head-Mounted Displays (XR HMDs) includes a requirement for well-functioning eyes and visual system. Eye and vision problems—that affect visual skills and abilities to various degrees—are common and may prevent an individual from comfortably wearing and using XR HMDs. Yet, vision problems have gained little attention in the XR community, making it difficult to assess the degree of accessibility and how to increase inclusivity. This perspective article aims to highlight the need for understanding, assessing, and correcting common eye and vision problems to increase inclusivity—to help broaden a responsible uptake of XR HMDs. There is a need to apply an interdisciplinary, human-centered approach in research. Guidelines are given for conducting reproducible research to contribute to the development of more inclusive XR technologies, through consideration of the individual variations in human visual skills and abilities.
